VALVE-OPERATING DEVICE.

Specification of Letters Patent.

Application filed August 11, 1911. Serial No. 643,565.

Allen and State of Indiana, have invented certain new and iusefulImprovements in Valve-Operating Devices, of which the following is aspecification.

This invention relates to improvements in valve operatingdevices of theclass used in connection with flushing tanks, and the object thereof isto provide a device of simple construction in which the operation, forwhich it is intended,imay be effected by moving a handle either upwardor downward. This object is accomplished by the construction illustratedin the ttccompanying drawings in which:

Figure 1 is a side elevation, partly in section and partly cut away,showing the operating mechanism inconnection with a flushing tank;andFig. 2 is a detailed View showing a plan of the oppositely disposedlevers and supporting brackets.

Similar numerals of reference indicate correspondingparts in bothviews,and referring now to the same: 1 is a flushing tank, and 2 is a liningof metal within the tank.

3 is a valve that rests upon; a seat 4 within the tank and closes thedischarge out-let 5. The out-let has in connection therewith anover-flow pipe 6 which extends up into the tank. The construction of.the out-let and over-flow pipe, the valve 3,. its stem 7 and guide 8,the valve lever 9 and link 10,

are of known construction and constitute the apparatus which thepresent. invention is intended to operate. The lever 9 is mounted upon ashaft 11 whichis supported in the upper part of the :tank :at its endsupon brackets 12, and it isthe intention that a downward pull upon therear end113 of the lever will effect the liftingof the valve 3 to permitthe. discharge from thetank through its outlet.

The invention comprises the two levers 14 and 15 which are oppositelydisposed and respectively mounted upon corresponding: shafts 16, thelatter being fixed in brackets 17 which are secured to the bottom of thetank 1.. The inner ends of the levers 14 and 1 15 are slotted as shownat 18 and lap one A 0011- 1 another so that the slots register. nectingrod .19 is secured at its upper endto the rear end 13 of the lever 9,and at. its lower end has connection with each of the levers 14 and 15,its end extending through said slots. Beneath the levers 14 and 15 ismounted an operating lever 20, the shaft.

21 affording a fulcrum therefor. The outer. ends of the levers 14 and 15are adaptedto be engaged and moved by the. lever, each having contactwith the lever, one upon one other upon the opposite side thereof, the

other of the levers 14 and 15 will be acted upon so as to draw theconnecting rod 19 downwardly and thereby actuate the valve lever.

What I claim as my invention and desire to secure by Letters Patent isIn a device of the class described, a valve mechanismlhaving a valvelever; a connect ingrod attached to the lever to actuatevthe same; twolevers pivotally mounted and dis posed oppositely to one another, theirends lapping and. each having a slot therein adapted to receive the endof the connecting rod; and an operating lever having its fulcrum in aplane lying between the pivotal supports of. the oppositely disposedlevers, and beingadapted to engage and actuate the said leversseverally.

In testimony whereof I afiix my signature, in presence of two witnesses.
